Triple

A triple, also called a three-base hit and abbreviated 3B, is a base hit that allows the batter to reach third base without the benefit of an error. 

A triple is also awarded when a player is thrown out at home plate trying for an inside the park home run. The triple is the least common of all hits and often the most difficult part of hitting for the cycle. Players who hit a lot of triples are usually speedsters who can take advantage of a batted ball finding a gap between outfielders and rolling all the way to the fence. The number of triples hit is also affected by the configuration of the ballpark: a park with a large outfield area and a distant fence will be more conducive to hitting triples that a bandbox.
